Use with Binoviewers
The Hyperion Universal Zoom Mark IV has an outermost diameter of just 55 mm,
which makes it a perfect choice for bino-viewers. People of all ages, even children
with an interpupillary distance of just 55 mm, can use a binoviewer with two Mark
IV Zoom-eyepieces – a big advantage e.g. for public observatories. The click-stops
greatly eases the quick change of magnification without even having to look at the
eyepiece scales.
By removing the height-adjustable eyecup, a huge gain in “nose space” is achieved.
The stepped eye-piece housing offers the dearly needed space for your nose, such it
becomes much easier to find the best viewing position to observe comfortably with two
eyepieces side by side. By choosing the winged eyecups instead of the height-adjust-
able ones, even wearers of glasses can observe comfortably with both eyes.
Note: we recommend the shorter adapter ring „A“
(for spotting scopes) also for observations with
bino-viewers, together with the 1¼" nosepiece. You
will gain ~4 mm of optical length compared to
using the adapter ring „B“ (for telescopes). Ob-
serving with any binoviewer regularly forces
the user to fight for every mm of back-fo-
cus in order to achieve a focused image,
just like when using a spotting scope.
The optional Hyperion Zoom Barlow Lens – 2,25x (#2956180)
The 2.25x Baader Hyperion Zoom Barlow lens was
designed especially to complement the Hyperion Zoom
eyepiece. It converts the regular focal lengths of 8 to 24
mm to a range of focal lengths between 3,6 and 10,7 mm,
while retaining the outstanding image quality for observing
sun, moon, planets and double stars with high resolution.
The Mark IV Zoom, in conjunction with or without the Hyper-
ion Barlow, covers all focal lengths between 3.6 to 24 mm.
The Hyperion Barlow works with every Hyperion 8-24 mm
Zoom eyepiece ever produced. The barlow is attached
onto the 1¼"-nosepiece. Because of the dual nosepiece
of the Mark IV, it can be used at telescopes with 1¼" or 2"
eyepiece clamps.
The pictures above show the Universal Zoom Mark IV
eyepiece together with the barlow, on the left for 1¼" and
on the right for 2" eyepiece clamps.
The Hyperion Barlow comes with a T-2
thread-adapter, to mount the Barlow in front of
any camera or other accessories with T-2-threads.
Combine it e.g. with a DSLR-camera – in this way
the camera body will be equipped with a 1 ¼"
nosepiece. The camera body just needs a stan-
dard T-ring to fit it onto any 1 ¼” eyepiece holder.

Attach the lens unit without the Barlow-adapter
(A) directly onto many 1¼" eyepieces, whenever
they do not already have an integrated barlow
element. The result is a 2x Barlow with very good
optical properties (see left image).
Some highlights of the Hyperion Zoom Barlow Lens:
• Triplet lens for highest optical quality
• Anastigmatic Flatfield Design for high sharpness all over the field of view
• Baader Phantom Coating
TM
Group for highest contrast and light transmission
Mounting at the eyepiece side:
• T-2 (M42x0,75mm) thread with Barlow-Adapter (B)
• Direct connection to any Hyperion Zoom eyepiece with Bar-
low-Adapter (A)
• 1¼" Filter thread without additional adapter
Please note:
The Barlow element can only be used with telescopes,
not with spotting scopes!
